Value Collection 534208PR Flat Socket Cap Screw M12x1.75

Product Description

The VALUE COLLECTION 534208PR is a metric flat socket cap screw engineered for applications requiring a flush or countersunk head profile. Manufactured from 12.9 grade alloy steel with a black oxide finish, this fastener delivers high tensile strength and moderate corrosion resistance. The 90-degree flat head seats into a matching countersunk hole, keeping the fastener surface flush with the workpiece. Drive engagement is through an 8 mm hex socket. Thread size is M12x1.75 with an overall length of 60 mm and partial threading along the shank. This screw is used primarily by machinists, millwrights, and maintenance technicians working in metal fabrication, machinery assembly, and structural equipment.

This flat socket cap screw is suited for bolted joints in ferrous and non-ferrous metal assemblies where a protruding head is not acceptable. Partial threading allows the unthreaded shank to act as a shoulder in clearance holes, helping align mating components. The black oxide finish is appropriate for interior or lightly oiled environments. Conforming to DIN 7991, this fastener meets a recognized international standard for flat-head socket screws and is dimensionally consistent with metric tooling and tapped hole specifications.

Key Features

• 12.9 material grade alloy steel for high tensile and proof load ratings
• 90-degree flat head for flush countersunk installation
• 8 mm hex socket drive for positive torque transfer
• M12x1.75 metric thread, partially threaded shank
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for M12x1.75 tapped holes in metal fabrication, machinery, and equipment assembly applications.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using an 8 mm hex key or socket driver. Countersink the mating hole to 90 degrees at the correct diameter to achieve full head seating before applying torque. Verify that the tapped hole thread specification matches M12x1.75 before installation to avoid cross-threading. De-energize and lock out any equipment before accessing fastened assemblies on powered machinery.
